Description

Measurement methods, devices and systems Technical Field

[0001] The present application relates to the field of communications, and in particular to a measurement method, device, and system. Background Art

[0002] Integrated communication and perception can leverage the transmission, reflection, and scattering of radio waves to perceive and characterize the environment, enabling high-precision positioning and tracking, gesture and activity recognition, and simultaneously enabling imaging, positioning, mapping, and human sensory enhancement. Currently, positioning terminals in a radio resource control (RRC) connected or RRC inactive state requires the target terminal to participate in signaling processing, resulting in additional power consumption, signaling overhead, and latency.

[0003] Summary of the Invention

[0004] The present application provides a measurement method, device, and system, wherein the measurement method can reduce the signaling overhead of a target device.

[0005] In a first aspect, a measurement method is provided, which is applied to a first network device and includes: sending first information and / or second information, where the first information is used to request the second network device to measure a first perception signal, where the first perception signal comes from the first network device or the second network device, and the second information is used to request the second network device to send a second perception signal; and obtaining a measurement result, where the measurement result is used to determine a perception feature of a target device, where the measurement result is determined based on the first measurement result and / or the second measurement result, where the first measurement result is obtained by measuring the first perception signal, and the second measurement result is obtained by measuring the second perception signal.

[0006] It should be understood that the transmission and reception of perception signals between the first and second network devices in this application must pass through the target device. For example, the first network device transmits a first perception signal, which is then transmitted by the target device and then reaches the second network device. Similarly, the second network device transmits a second perception signal, which is then transmitted by the target device and then reaches the first network device. For the sake of simplicity, this application describes the first network device sending a perception signal to the second network device, or the second network device sending a perception signal to the first network device.

[0007] In this method, the first and second network devices obtain the target device's perception characteristics by measuring perception signals. The target device does not need to participate in signaling interactions, reducing its signaling overhead. Furthermore, even when the target device is in an idle state, the network devices can still perform perception measurements on it, expanding the application scenarios of perception measurements.

[0008] It should be understood that in the present application, the first network device and the second network device respectively perform self-sensing and transmit-receive separation sensing, which can enhance diversity sensing performance and improve sensing accuracy and sensing robustness.

[0009] In certain implementations, the first perception signal comes from the first network device, and the first information is further used to indicate a configuration of the first perception signal, where the configuration of the first perception signal includes at least one of the following information:

[0010] The cyclic prefix corresponding to the first perception signal, the time domain resources and / or frequency domain resources carrying the first perception signal, the subcarrier spacing of the frequency domain resources carrying the first perception signal, the beam carrying the first perception signal, the reception time range of the second network device, the perception distance range of the second network device, or the transmission time range of the first network device.

[0011] In this manner, the first network device indicates the configuration of the sensing signal from the first network device to the second network device, so that the second network device can accurately receive the sensing signal.

[0012] In some implementations, the first information further indicates a first parameter, where the first parameter is used to determine the measurement result; the second parameter includes a first measurement quantity, where the first measurement quantity includes at least one of the following information:

[0014] In this method, the first network device configures measurement quantities, or configures perception requirements, for the second network device. That is, the first network device requires the quantity measured by the second network device, so as to avoid the measurement results of the second network device failing to meet the requirements of the first network device, thereby improving the measurement efficiency of the second network device.

[0015] It should be understood that the first measurement value is the value fed back by the second network device to the first network device after the measurement is completed.

[0171] First, a brief introduction to the network architecture applicable to the embodiments of the present application is given as follows.

[0172] FIG1 is a schematic diagram of a wireless communication system 100 applicable to an embodiment of the present application. As shown in FIG1 , the wireless communication system 100 may include at least one network device, such as the network device 110a shown in FIG1 . The wireless communication system 100 may also include at least one terminal device, such as the terminal device 120a and the terminal device 120b shown in FIG1 . Both the network device and the terminal device may be configured with multiple antennas, and the network device and the terminal device may communicate using multi-antenna technology. Terminal devices may also communicate with each other. For example, terminal devices may communicate directly with each other. For another example, terminal devices may communicate with each other through other communication devices, such as network devices or other terminal devices.

[0173] When a network device communicates with a terminal device, the network device can manage one or more cells, and a cell can have an integer number of terminal devices. Optionally, network device 110a and terminal device 120a form a single-cell communication system. Without loss of generality, the cell is referred to as cell #1. Network device 110a can be a network device in cell #1, or network device 110a can serve a terminal device (e.g., terminal device 120a) in cell #1.

[0174] It should be noted that a cell can be understood as an area within the coverage range of wireless signals of network equipment.

[0175] It should be understood that Figure 1 is a simplified schematic diagram for ease of understanding, and the wireless communication system 100 may also include other network devices or other terminal devices, which are not shown in Figure 1. The embodiments of the present application can be applied to any communication scenario in which a transmitting device and a receiving device communicate.

[0176] To facilitate understanding of the embodiments of the present application, the following is a brief explanation of the terms involved in the embodiments of the present application.

[0177] 1. Perception: In the communications field, perception refers to acquiring environmental information through a sensory network, such as target positioning, imaging, detection, and tracking. This perception information can be used to optimize and enhance communication systems, such as avoiding obstacles and improving communication quality. Perception can also be used for channel modeling and signal analysis in wireless communication systems, leading to a better understanding and optimization of communication performance.

[0178] 2. Self-perception: In this application, self-perception refers to the ability to measure the perceived target by receiving a perception signal emitted by the device itself. For example, in wireless communications, self-perception can include the perception of the wireless channel, the perception of the transmit power, the perception of the signal quality, etc. For example, the transmitter transmits a perception signal, which is reflected by the perception target and then received by the transmitter. The transmitter can obtain the distance to the perception target based on the transmission time and reception time of the perception signal. Self-perception technology has applications in many fields, such as smart transportation, smart cities, and smart homes.

[0179] 3. Perception with separated transmit and receive: In this application, separated transmit and receive perception refers to performing the two functions of receiving and sending independently. Separate transmit and receive perception can achieve better signal reception and transmission effects, and can also reduce system complexity and improve system stability. For example, a separate transmit and receive perception system includes two parts: a transmitter and a receiver. The transmitter is responsible for transmitting the perception signal, which is received by the receiver after being reflected by the perception target. The receiver processes the perception signal and obtains information about the perception target. Separate transmit and receive perception technology has applications in many fields, such as wireless communications, satellite communications, radar, etc. This technology can improve the transmission efficiency and reliability of the communication system, and can also reduce the complexity and cost of the system.

[0180] 4. Synchronous Equipment Management Function (SEMF): In the communications field, SEMF is a perception management functional block used to manage communications equipment. Alternatively, in the field of communication convergence perception, SEMF is a perception management functional block used to manage communications equipment or communication convergence perception equipment. The role of SEMF is to collect status information from other functional blocks and perform corresponding management operations, including issuing commands to each functional block, collecting alarm performance events from each functional block, transmitting operation, management, and maintenance (OAM) information to other network elements via data communication channels (DCC), and reporting equipment alarm performance data to the network management terminal.

[0181] Positioning is one of the capabilities of perception. 5G NR has standardized air interface positioning and supports positioning management functions in the core network for resource coordination and scheduling related to positioning, as well as determination of target location, speed estimation of measurement signals, and measurement accuracy. The positioning management function is located in the core network and can respond to positioning requirements from external parties or UEs. In addition, the positioning of a UE in an RRC connected state or an RRC inactive state requires the participation of the UE, such as the UE's participation in information transmission and reception, such as the UE measuring and reporting the positioning reference signal sent by the base station, or the UE sending an SRS for measurement by the base station.

[0182] Currently, the core network's positioning management, or perception, is unable to detect and locate passive and idle UEs, failing to achieve the desired perception goals. Perception and positioning of RRC-inactive UEs increases UE power consumption and signaling overhead, incurring additional latency. Perception and positioning of RRC-connected UEs, when there is no data transmission or no on-link opportunity, results in additional power consumption, signaling overhead, and latency. The acquisition of positioning information for both the UE and the network requires the core network's LMF location management function, hindering the latency requirements of low-latency positioning.

[0183] In view of this, the present application proposes a measurement method, as shown in FIG2 , which includes the following steps:

[0184] 210 , the first network device sends information # 1 and / or information # 2 to the second network device. Correspondingly, the second network device receives the information # 1 and / or information # 2.

[0185] Message #1 (i.e., an example of the first message) is used to request the second network device to measure perception signal #1 (i.e., an example of the first perception signal). Perception signal #1 originates from the first network device. Specifically, the first network device transmits perception signal #1, which is received and measured by the second network device. For example, as shown in FIG3 , the first network device transmits perception signal #1, which is reflected by the target device and then received by the second network device.

[0186] Message #2 (another example of the first message) is used to request the second network device to measure perception signal #2 (another example of the first perception signal). Perception signal #2 originates from the second network device. Specifically, the second network device transmits perception signal #2 and receives and measures perception signal #2. In other words, message #2 requests the second network device to perform self-perception. For example, as shown in Figure 4, the second network device transmits perception signal #2, which is then reflected by the target device and received by the second network device.

[0187] Information #3 (i.e., an example of the second information) is used to request the second network device to send perception signal #3 (i.e., an example of the second perception signal). For example, as shown in FIG5 , the second network device sends perception signal #3, which is reflected by the target device and received by the first network device.

[0188] Optionally, the perception signal #3 may be the same as or different from the perception signal #2. In other words, the perception signal #3 may be a signal reflected from the perception signal #2, or may be a perception signal sent by the second network device in addition to the perception signal #2.

[0189] For example, the second network device sends a sensing signal #2, receives the sensing signal #2 for measurement, and the sensing signal #2 is reflected by the target device and then received by the first network device, which measures the sensing signal #2.

[0190] For another example, the second network device sends sensing signal #2, receives sensing signal #2 for measurement, and sends sensing signal #3, which is reflected by the target device and received by the first network device. The first network device measures sensing signal #3.

[0191] The following describes information #1, information #2, and information #3 respectively.

[0192] 1. Information #1

[0193] The information #1 is used to request the second network device to measure the sensing signal #1.

[0194] In one possible embodiment, information #1 indicates parameter A, i.e., the configuration of perception signal #1. For example, parameter A is used to indicate the configuration of perception signal #1. Alternatively, parameter A is used to configure perception signal #1. Alternatively, parameter A is used by the second network device to receive perception signal #1.

[0195] Parameter A includes at least one of the following: a cyclic prefix corresponding to the perception signal #1, a time-frequency resource carrying the perception signal #1 (that is, a time domain resource and / or a frequency domain resource, the explanation of the time-frequency resource in this application can be referred to here), a subcarrier spacing of the frequency domain resource carrying the perception signal #1, a beam carrying the perception signal #1, a receiving time window range of the second network device, or a perception distance range of the second network device, or a sending time window range of the first network device.

[0196] The transmission time window range (also referred to as the transmission time range) of the first network device can be understood as the range of the time window within which the first network device transmits the perception signal. For example, the range of the time window within which the first network device transmits perception signal #1. It should be understood that the transmission time window of the first network device can be used to transmit perception signal #1 or to transmit other information besides perception signals.

[0197] The receiving time window range (also referred to as the receiving time range) of the second network device can be understood as the range of the time window within which the second network device receives the perception signal. For example, the range of the time window within which the second network device receives perception signal #1. It should be understood that the receiving time window of the second network device can be used to receive perception signal #1, other perception signals, or information other than perception signals.

[0198] The receiving time window of the second network device is related to the geographical range to be sensed, the reflection, diffraction, and stray radiation of the sensing environment on the signal, etc. It reflects the distance range of the sensing target and affects the time range of the second network device to detect the sensing signal.

[0199] When the sending time window of the first network device is the sending time window of the perception signal #1, and the receiving time window of the second network device is the receiving time window of the perception signal #1, the ranges (or time lengths) of the two time windows may be equal.

[0200] The perception distance range of the second network device, i.e., the perception distance configured by the first network device for the second network device, is within a certain range. For example, the perception distance range is determined based on the target device. For example, the perception distance range can cover the target device. For example, the distance between the target device's location and the second network device's location is less than or equal to the perception distance range of the second network device.

[0201] For example, the parameter corresponding to the beam carrying perception signal #1 can be the index of the beam. That is, information #1 includes the index of the beam carrying perception signal #1, and the first network device indicates the beam to the second network device via information #1. It should be understood that the method of indicating beams is not limited to indexes, and other methods that can distinguish different beams are also within the scope of protection of this application, such as predefining the order and identification of beams in the first and second network devices.

[0202] The time-frequency resources carrying perception signal #1 include time domain resources and / or frequency domain resources. The time-frequency resources carrying perception signal #1 can be understood as the time-frequency resources configured for perception signal #1. It can be understood that the first network device indicates the time domain resources carrying perception signal #1 to the second network device, and the second network device can determine the time to receive perception signal #1 based on the time domain resources. In other words, the first network device indicating the time domain resources carrying perception signal #1 is equivalent to indicating the transmission time or transmission time range of perception signal #1 (i.e., the transmission time window range of the first network device) to the second network device.

[0203] The information #1 also indicates parameter B (ie, the first parameter).

[0204] Parameter B is used to determine the measurement result. For example, parameter B includes a first measurement quantity, and the first measurement quantity includes at least one of the following information:

[0205] the distance between the second network device and the target device, the speed of the target device, the angle of the target device, the time delay of the second network device receiving the sensing signal #1, the signal strength of the sensing signal #1, the Doppler frequency shift of the sensing signal #1, or the measurement time of the second network device.

[0206] It should be understood that the first measurement value is content configured for the second network device to measure, and is also content configured for the second network device to report.

[0207] That is, the second network device measures the distance between the second network device and the target device, the speed of the target device, the angle of the target device, the time delay of the second network device receiving the perception signal #1, the signal strength of the perception signal #1, the Doppler shift of the perception signal #1, or the measurement time of the second network device, and feeds back at least one of these quantities to the first network device.

[0208] The distance between the second network device and the target device is the distance between the second network device and the target device obtained by the second network device receiving and measuring the sensing signal #1 reflected by the target device.

[0209] The speed of the target device, ie, the moving speed of the target device, is measured by the second network device.

[0210] The target device angle is the angle between the target device and the second network device, measured by the second network device. The target device angle includes the angle of departure (DoA) and / or angle of arrival (AoA) of the sensing signal.

[0211] The delay of the second network device receiving the perception signal # 1 can be understood as the time length used by the second network device to receive the perception signal # 1 .

[0212] For example, the signal strength of the sensing signal #1 may be represented by a received signal strength indicator (RSSI) or a received signal power (RSRP).

[0213] The Doppler shift of the sensing signal #1 is a measurement of the frequency offset between the sending and receiving of the sensing signal, which can be used to estimate the moving speed of the target device.

[0214] The measurement time of the second network device is the time when the second network device measures the sensing signal # 1 , or in other words, the time when the second network device senses the target device.

[0215] Parameter B also includes at least one of the following information:

[0216] The first measurement quantity includes the component of each multipath path, the index of the beam carrying sensing signal #1, or the type of feedback quantity. The feedback quantity is either the first measurement quantity or the processed first measurement quantity. In other words, the feedback quantity type is divided into raw quantity and processed quantity. The raw quantity is the first measurement quantity, and the processed quantity is the processed first measurement quantity.

[0217] The first measurement quantity includes the components of each multipath path, such as received signal strength or power, delay, angle of arrival, loss of service (LOS) probability, or non-local operating system (NLOS) probability. Multipath sensing measurements can distinguish multipath components, leading to more accurate perception, such as distance or angle.

[0218] The second network device feeds back the index of the beam carrying the sensing signal # 1 to the first network device, so that the first network device determines the corresponding beam.

[0219] The feedback amount may be a raw measurement amount or a processed measurement amount. That is, the second network device may feed back the first measurement amount to the first network device, or may feed back the first measurement amount after processing.

[0220] It should be understood that the above-mentioned parameter A is the parameter corresponding to perception signal #1, or in other words, the parameter configured by the first network device for the second network device to receive and measure perception signal #1. The parameters corresponding to different perception signals may be different. For example, information #1 also indicates the configuration of perception signal #3, and the configuration of perception signal #3 differs from the configuration of perception signal #1 in at least one aspect. For example, the beam of perception signal #3 differs from the beam of perception signal #1. Another example is that the subcarrier spacing of the frequency domain resources of perception signal #3 differs from the subcarrier spacing of the frequency domain resources of perception signal #1.

[0221] It should be understood that the configuration of perception signal #3 may also be the same as the configuration of perception signal #1.

[0222] The parameter B is obtained by the second network device receiving and measuring the sensing signal #1, and corresponds to the sensing signal #1. The measurement results of different sensing signals may be different.

[0223] Optionally, when both the first network device and the second network device have a sensing management function, the first network device can process the measurement quantity, and the second network device can also process the measurement quantity. When the first network device configures the second network device to process the first measurement quantity. Parameter B also includes:

[0224] The sending angle of the perception signal #1, the coordinate system used by the first network device to send the perception signal #1, and the sending timestamp of the perception signal #1.

[0225] The sending angle of the perception signal #1 is also the angle of the beam used by the first network device to send the perception signal #1.

[0226] The coordinate system of the perception signal #1 is the global coordinate system. Alternatively, it can be the local coordinate system and the conversion coefficient between the local coordinate system and the global coordinate system.

[0227] The transmission timestamp of perception signal #1 is the transmission time, which can be represented by a frame, a time slot, a symbol, or a sampling time. The second network device can calculate the time when the perception signal was transmitted from the first network device to the second network device based on the transmission time of the perception signal by the first network device and the reception time of the perception signal by the second network device.

[0228] 2. Information #2

[0229] The information #2 is used to request the second network device to measure the perception signal #2. In other words, the information #2 is used to request measurement feedback of the perception signal 2.

[0230] In one possible manner, the information #2 indicates parameter C (ie, the second parameter), and the parameter C is used to determine the second measurement result.

[0231] The parameter C includes a second measurement quantity, and the second measurement quantity includes at least one of the following information:

[0232] The distance between the target device and the first network device, the speed of the target device, the angle of the target device, the signal strength of perception signal #2, the transmission delay of perception signal #2 (also known as transmission delay, i.e., the time taken for perception signal #2 to be sent and received), and the Doppler frequency shift of perception signal #2.

[0233] The speed, angle, signal strength, transmission delay, Doppler frequency domain, and measurement time of the sensing signal can all be referred to the description in parameter B.

[0234] Parameter C also includes a perception requirement, which includes at least one of the following:

[0235] Feedback delay requirements, feedback cycle, measurement accuracy requirements or measurement resolution requirements,

[0236] Parameter C also includes at least one of the following:

[0237] The measurement time and / or number of the second network device, the geographical location range of the target device, the time range of the perception signal sent by the second network device, the components of the second measurement amount in each path in the multipath (also referred to as each multipath component), the timing error group identifier of the measurement result, the timing error group identifier corresponding to the self-perception transmission and reception, the timing error group identifier corresponding to the reception timing error group identifier of the transmission and reception separation, and the perception signal resource of the first network device used for the measurement or the type of feedback amount, the feedback amount is the second measurement amount or the processed second measurement amount.

[0238] The multipath in this application can correspond to physical multipath. For example, a perception signal may be sent along multiple, different transmission paths, resulting in the perception signal arriving at the receiving device at different times. In other words, multipath causes the same perception signal to arrive at the receiving device with varying delays. Physical multipath can also correspond to different spatial paths, causing the receiving device to receive the perception signal from different angles.

[0239] The number of measurements by the second network device can be understood as the number of times the second network device receives the perception signal #2. For example, the perception signal #2 can be sent multiple times within a certain time range, and the second network device can receive the perception signal #2 multiple times.

[0240] The first network device indicates the geographic location range of the target device to the second network device, which helps the second network device determine the direction of the beam carrying the sensing signal, or in other words, helps the second network device determine the direction in which to send the sensing signal #2.

[0241] Timing error group identification of measurement results: Signals passing through different transmitting or receiving hardware devices, such as RF channels and antennas, may cause different delays. When using different hardware devices to send and / or receive signals, different time / timing errors will be generated. When reporting or feeding back measurement results, measurement results processed using the same hardware are grouped together. Measurement results within this group have the same or similar timing errors. There are further groups such as transmit timing error groups, receive timing error groups, and transmit and receive timing error groups. This allows devices receiving measurement results to process them separately, while feedback results from the same group at different times can be processed uniformly, such as by averaging. This helps control error propagation and ensure the accuracy of measurement results.

[0242] The timing error group identifier also includes a timing error group identifier corresponding to the self-sensing sending and receiving and / or a timing error group identifier corresponding to the receiving and sending separation.

[0243] The sensing signal resources of the second network device used for measurement, such as time domain resources and / or frequency domain resources used by the second network device to send the sensing signal.

[0244] The time range of perception signal transmission, the components of the measurement amount in each path in the multipath, the feedback amount, etc. can be referred to the explanation in parameter A. The difference is that the parameters here correspond to perception signal #2 and are not repeated here.

[0245] In summary, parameter C is the measurement requirement configured by the first network device for the second network device, such as the measurement amount, perception requirement, feedback requirement, etc. of the second network device. The second network device can autonomously determine the configuration of perception signal #2 based on these configurations.

[0246] For example, the cyclic prefix corresponding to the perception signal #2, the time-frequency resources carrying the perception signal #2, the subcarrier spacing of the frequency domain resources carrying the perception signal #2 or the beam carrying the perception signal #2, the receiving window time range of the second network device self-perception, and the number of times the second network device sends the perception signal #2, receives the perception signal #2, and measures the perception signal #2.

[0247] Optionally, the second network device sends the autonomously determined configuration (full configuration or partial configuration) of the perception signal #2 to the first network device.

[0248] In another possible manner, information #2 indicates a third parameter, and the third parameter includes at least one of the following information:

[0249] The cyclic prefix corresponding to perception signal #2, the time-frequency resources carrying perception signal #2, the subcarrier spacing of the frequency domain resources carrying perception signal #2 or the beam carrying perception signal #2, the receiving window time range of the second network device self-perception, the number of times the second network device sends perception signal #2, receives perception signal #2, measures perception signal #2, and feedback delay requirements.

[0250] Specifically, the parameters can refer to the above explanations and will not be repeated here.

[0251] In this manner, the first sensing device configures the second sensing device with parameters for sending or measuring the sensing signal #2, and the second sensing device performs the sending and / or measurement according to these parameters.

[0252] 3. Information #3

[0253] The information #3 is used to request the second network device to send a sensing signal #3.

[0254] In one possible approach, the first network device configures sensing requirements for the second network device, and the second network device autonomously determines measurement parameters based on these requirements. For example, information #3 indicates parameter D (i.e., the fourth parameter). For example, parameter D includes at least one of the following: measurement accuracy requirements or measurement resolution requirements, the geographic location range of the target device, and the time range for transmitting sensing signals by the second network device or the time range for receiving sensing signals by the first network device.

[0255] Specifically, the explanation of each parameter can refer to the above description, the difference is that each parameter here corresponds to the perception signal #3.

[0256] Optionally, the second network device may feed back the transmission parameters determined based on the sensing requirement to the first network device. For example, the second network device may send information A to the first network device, where the information A indicates the cyclic prefix corresponding to sensing signal #3, the time-frequency resources carrying sensing signal #3, the subcarrier spacing of the frequency domain resources carrying sensing signal #3, or the beam carrying sensing signal #3.

[0257] For example, information A indicates a beam carrying perception signal #3, and the beam may be indicated by an index of the beam indicating perception signal #3.

[0258] In another possible approach, the first network device directly configures transmission parameters for the second network device, and the second network device transmits perception signal #3 according to the transmission parameters. For example, information #3 indicates parameter E (i.e., the fifth parameter), and parameter E includes at least one of the following: the cyclic prefix corresponding to perception signal #3, the time-frequency resources carrying perception signal #3, the subcarrier spacing of the frequency domain resources carrying perception signal #3, or the beam carrying perception signal #3.

[0259] It should be understood that when perception signal #3 is the same as perception signal #2, the first network device can send a single message to the second network device to simultaneously instruct both measurement methods. For example, the first network device can send message #2 to the second network device to both instruct the second network device to perform self-perception and to instruct the second network device to send a perception signal to the first network device.

[0260] 220. The first network device obtains a measurement result, where the measurement result is determined based on the first measurement result, the second measurement result, and / or the third measurement result.

[0261] The first measurement result is obtained based on the perception signal #1, the second measurement result is obtained based on the perception signal #2, and the third measurement result is determined based on the perception signal #3. The measurement results are used to determine the perception characteristics of the target device.

[0262] For example, sensing signal #1 is used for self-sensing by the first network device and is also used by the second network device to perform transceiver separation sensing. Sensing signal #2 is used for self-sensing by the second network device, and the first network device can perform transceiver separation sensing with the aid of sensing signal #2 or sensing signal #3. The first measurement result is obtained based on sensing signal #1. The first measurement result can be the self-sensing result of the first network device, the transceiver separation sensing result obtained by the second network device by measuring sensing signal #1, or the self-sensing result of the first network device and the transceiver separation sensing result obtained by the second network device by measuring sensing signal #1. The second measurement result can be the self-sensing result obtained by the second network device by measuring sensing signal #2, the transceiver separation sensing result obtained by the first network device by measuring sensing signal #2, or the self-sensing result obtained by the second network device by measuring sensing signal #2 and the transceiver separation sensing result obtained by the first network device by measuring sensing signal #2. The third measurement result can be the transceiver separation sensing result obtained by the first network device by measuring sensing signal #3.

[0263] Optionally, when the perception signal #2 and the perception signal #3 are the same, the third measurement result is also the same as the second measurement result.

[0264] The measurement result is determined based on the first measurement result, the second measurement result and / or the third measurement result. For example, the measurement result may be a result of comprehensive processing of the first measurement result, the second measurement result and / or the third measurement result.

[0265] The measurement result is used to determine the perceptual characteristics of the target device, or in other words, the measurement result is used to indicate the perceptual characteristics of the target device. The perceptual characteristics of the target device may be the position, distance, speed, angle, shape, posture, or image of the target device.

[0266] That is, the second network device feeds back the measurement results obtained by the second network device, such as the second network device's self-sensing results and the transmission-reception separation perception results, to the first network device. The first network device determines a final measurement result based on the measurement results fed back by the second network device and the measurement results obtained by the first network device, such as the first network device's self-sensing results and the transmission-reception separation perception results, to obtain the perception characteristics of the target device.

[0267] Optionally, collecting the measurement results and processing the measurement results may also be completed by the second network device.

[0268] Alternatively, one of the first network device and the second network device collects the measurement result and feeds it back to the other device, and the other device processes the measurement result.

[0269] It should be understood that in the above method, both the first network device and the second network device support the awareness management function.

[0270] The target device mentioned above may be a network device or a terminal device. The target device below can refer to the explanation here and will not be described in detail.

[0271] In this method, the first network device interacts with the second network device to complete measurement (or perception) of the target device without the participation of the target device, thereby reducing the signaling overhead of the target device.

[0272] To facilitate understanding of the method of the embodiment of the present application, FIG6 shows a schematic diagram of a measurement process. RAN device 1 is used as an example of a first network device, and RAN device 2 is used as an example of a second network device. It should be understood that the sensing management function entity can be located in the RAN and / or the core network. Here, the sensing management function entity is located in the RAN as an example. The process includes the following steps:

[0273] 610. RAN devices acquire duplex capability and interact to determine whether the other party supports the SEMF function.

[0274] The duplex capability is sensed to be full duplex or half duplex, which affects the reception time of the sensed signal. In this illustration, both RAN device 1 and RAN device 2 support SEMF.

[0275] 620 , RAN device 1 sends collaborative awareness request message 1 (an example of information # 1 ) to RAN device 2 , and correspondingly, RAN device 2 receives collaborative awareness request message 1 .

[0276] The cooperative sensing request message 1 is used for separate sensing (sent by RAN device 1 and received by RAN device 2). RAN device 1 notifies RAN device 2 of the receiving parameter configuration at the Uu interface and the measurement configuration of RAN device 2 at the Uu interface and feedback configuration at the Xn interface through the Xn interface.

[0277] Among them, the parameters included in the collaborative sensing request message 1 can refer to parameter A. For example, the sensing parameter set or sensing format sent by the RAN device 1 includes one or more of the following: cyclic prefix (CP), subcarrier spacing (SCS), time-frequency resources, beam indication, and receiving time window. The receiving time window is a beam-specific or unified sensing receiving time window range. The configuration of multiple sensing windows or a unified sensing window can reflect the sensing range requested by the RAN device 1. The RAN device 2 obtains the sensing range requested by the RAN device 1 by receiving the configuration of the RAN device 1; the corresponding receiving time window can be a continuous coverage of multiple formats (or corresponding to multiple beams), or a separate receiving time window for each format or each beam. It is related to whether the time configurations of each sensing format are continuous. If the time configurations of each sensing format are continuous, a continuous receiving window time can be configured to perform multi-format sensing signal reception detection.

[0278] Optionally, there may be multiple sets of parameter sets, and the multiple parameter sets may have different SCSs, such as different SCSs of RAN device 1 representing different minimum coverage distances. Multi-format parameters may correspond to the transmission of multi-beam scanning perception signals. By configuring multiple sets of perception signal parameters, cooperative perception with separated transmission and reception is supported between different devices, which can enhance diversity perception performance and improve perception accuracy and perception robustness. Through multi-beam scanning, the probability of the perception signal being captured by the cooperative device (such as the RAN device 2 here) can be increased. Through multi-beam scanning perception, the probability of the perception signal being captured by the target device can be increased.

[0279] The parameters included in the collaborative awareness request message 1 can also refer to the introduction of the above parameter B and will not be repeated here.

[0280] 630 , RAN device 1 sends collaborative awareness request message 2 (an example of information # 2 ) to RAN device 2 , and correspondingly, RAN device 2 receives collaborative awareness request message 2 .

[0281] The collaborative perception request message 2 is used through the Xn port to request the RAN device 2 to perform self-perception and measurement at the Uu port, and to feed back to the RAN device 1 at the Xn port; and / or, through interaction at the Xn port, supports the RAN device 1 to perform separated transmission and reception perception based on the perception signal of the RAN device 2 (RAN device 2 sends the perception signal, and RAN device 1 receives the perception signal).

[0282] Specifically, the content indicated by the collaborative perception request message 2 can refer to the content of information #2 above and will not be repeated here.

[0283] 640 , RAN device 1 sends perception signal A (an example of perception signal # 1 ) to RAN device 2 at Uu. Correspondingly, RAN device 2 receives the perception signal A.

[0284] The RAN device 1 sends the perception signal A according to the parameters notified to the RAN device 2 at Xn in 620 .

[0285] 650 , RAN device 1 performs self-sensing measurement, and RAN device 2 performs reception measurement with transmit-receive separation sensing.

[0286] 660 , RAN device 2 sends feedback message 1 to RAN device 1 , and correspondingly, RAN device 1 receives feedback message 1 .

[0287] For example, RAN device 2 sends feedback message 1 to RAN device 1 at Xn. Feedback message 1 is used to feed back measurement results of RAN device 2 based on the sensed signal of RAN device 1.

[0288] Optionally, the feedback message 1 carries the ID of the sensing signal A and / or the ID of the RAN device 2 to distinguish which sensing signal the measurement result belongs to and from which device.

[0289] 670 , RAN device 2 sends feedback message 2 to RAN device 1 , and correspondingly, RAN device 1 receives feedback message 2 .

[0290] For example, RAN device 2 sends feedback message 2 to RAN device 1 at Xn. Feedback message 2 is used to feed back the configuration of the sensing signal of RAN device 2 and / or whether the current cooperative sensing is supported.

[0291] 680 , the RAN device 2 determines to feed back the sensing measurement value or the synthesized sensing calculation result.

[0292] If RAN device 1 requests RAN device 2 to feedback the measurement value, RAN device 2 performs the measurement value feedback. Otherwise, when RAN device 2 supports SEMF, RAN device 2 can directly feedback the perception calculation result when RAN device 1 requests feedback of the perception calculation result.

[0293] 690 , RAN device 2 sends perception signal B to RAN device 1 , and correspondingly, RAN device 1 receives the perception signal B.

[0294] Specifically, RAN device 2 sends perception signal B to RAN device 1 according to collaborative perception request message 2 in 630 .

[0295] When RAN device 2 autonomously determines the perception format of perception signal B, it autonomously configures the parameters for sending perception signal B {such as CP / SCS / perception signal time-frequency resources / beam} in combination with the reception time of RAN device 1 in 630, and sends it to RAN device 1 through a feedback message, so that RAN device 1, as a receiving device with separate transmission and reception, measures the perception measurement results.

[0296] At 6100 , RAN device 2 performs self-sensing measurement, and RAN device 1 performs receiving sensing measurement with separation of transmit and receive.

[0297] 6110 , RAN device 2 determines to feed back a perception measurement value or a synthesized perception calculation result based on whether the SEMF function is supported and the request of RAN device 1 .

[0298] If RAN device 1 requests RAN device 2 to feedback the measurement value, RAN device 2 will feedback the measurement value. Otherwise, when RAN device 2 supports SEMF, if RAN device 1 requests feedback of the perception calculation result, RAN device 2 can directly feedback the perception calculation result.

[0299] 6120 , RAN device 2 sends feedback message 3 to RAN device 1 , and correspondingly, RAN device 1 receives feedback message 3 .

[0300] For example, RAN device 2 sends feedback message 3 to RAN device 1 at Xn. Feedback message 3 is used to feed back the self-sensing measurement result of RAN device 2.

[0301] 6130 , the RAN device 1 synthesizes, calculates and / or identifies the target based on the received perception results.

[0302] It should be understood that the collaborative awareness request message 1 and the collaborative awareness request message 2 can be combined into different request information in one message. Feedback messages can also be combined, such as feedback messages 1 and 2, but they are still different information.

[0303] Furthermore, the process of the method is summarized as shown in Figure 7. It should be understood that the measurement process, or the embodiments of the present application, can also be applied to passive / idle / inactive terminals or low-power terminals for sensing and detection.

[0304] The self-sensing and transmit-receive separation sensing of the RAN device 1 (or the first network device) is shown in Figure 8. The self-sensing and transmit-receive separation sensing of the RAN device 2 (or the second network device) is shown in Figure 9. A sensing entity is deployed in both RAN devices 1 and 2.

[0305] Another measurement method is described below, in which the first network device supports the perception management function, while the second network device does not support the perception management function. As shown in FIG10 , the method includes:

[0306] 1010. The first network device sends information #4 and / or information #5 to the second network device. Correspondingly, the second network device receives the information #4 and / or information #5.

[0307] Among them, information #4 can refer to the description of information #1 in Figure 2, and information #5 can refer to the description of information #2, which will not be repeated here.

[0308] Information #5 is used to indicate parameter F, which includes at least one of the following:

[0309] The cyclic prefix corresponding to perception signal #4, the time-frequency resources carrying perception signal #4, the subcarrier spacing of the frequency domain resources carrying perception signal #4 or the beam carrying perception signal #4, the receiving window time range of the second network device self-perception, the number of times the second network device sends perception signal #4, receives perception signal #4, measures perception signal #4, or feedback delay requirements.

[0310] 1020. The first network device obtains a measurement result, where the measurement result is determined based on the first measurement result and / or the second measurement result.

[0311] For descriptions of the measurement results, first measurement results, and / or second measurement results, refer to the description in 220 and are not repeated here. The difference is that, because the second network device does not have an SEMF, it cannot process the measurement results. Therefore, processing of the measurement results can be completed by the first network device. Furthermore, the second network device cannot autonomously determine perception parameters and does not need to feedback autonomously configured perception parameters, because the second network device's self-perception configuration is configured by the first network device.

[0312] To facilitate understanding of the method of the embodiment of the present application, FIG11 shows a schematic diagram of a measurement process. RAN device 1 is used as an example of a first network device, and RAN device 2 is used as an example of a second network device. The process includes the following steps:

[0313] 1110. RAN devices acquire duplex capability and interact to determine whether the other party supports the SEMF function.

[0314] The duplex capability is sensed to be full duplex capability or half duplex capability, which affects the reception time of the sensing signal. In this illustration, the RAN device 1 supports SEMF.

[0315] 1120 , RAN device 1 sends collaborative awareness request message 3 (an example of information # 4 ) to RAN device 2 , and correspondingly, RAN device 2 receives collaborative awareness request message 3 .

[0316] Collaborative sensing request message 3 is used for separate sensing (RAN device 1 sends a sensing signal, and RAN device 2 receives the sensing signal). RAN device 1 informs RAN device 2 of: RAN device 1's sensing parameters, including CP / SCS, time-frequency resources, beam, RAN device 1's Rx window time range or RAN device 2's sensing reception time window range or RAN device 2's sensing distance range, to reflect the sensing range requested by RAN device 1; the number of reception measurements (before reporting) by RAN device 2, or the Xn port feedback delay requirement.

[0317] 1130 , RAN device 1 sends collaborative awareness request message 4 (another example of information # 4 ) to RAN device 2 , and correspondingly, RAN device 2 receives collaborative awareness request message 4 .

[0318] Collaborative Sensing Request Message 4 is used to request RAN device 2 to perform self-sensing and / or RAN device 1 to perform separate transmit / receive sensing based on RAN device 2's sensing signals (RAN device 2 transmits sensing signals, RAN device 1 receives sensing signals). RAN device 1 directly configures the sensing parameters used by RAN device 2, which may include {Tx CP / SCS / time-frequency resources, Rx window / GP}. In this case, there is no need to notify RAN device 1 of the reception time range for receiving signals. RAN device 1 can also directly configure the number of transmit and receive measurements (before reporting) and / or the Xn interface feedback latency requirement for RAN device 2.

[0319] 1140. RAN device 1 sends perception signal #4 to RAN device 2. Correspondingly, RAN device 2 receives perception signal #4.

[0320] For example, RAN device 1 sends a perception signal # 4 to RAN device 2 based on the content of cooperative perception request message 3 .

[0321] 1150 , RAN device 1 performs self-sensing measurement.

[0322] That is, the RAN device 1 receives the sensing signal #4 sent by itself and completes the self-sensing measurement.

[0323] 1160 , RAN device 2 performs reception perception measurement with transmission and reception separation.

[0324] That is, the RAN device 2 receives the perception signal #4 and completes the reception perception measurement with separate transmission and reception.

[0325] 1170 , RAN device 2 sends feedback message A to RAN device 1 , and correspondingly, RAN device 1 receives feedback message A.

[0326] The feedback message A is used by the RAN device 2 to feed back the measurement result of the perception signal #4 to the RAN device 1 at Xn.

[0327] 1180 , RAN device 2 sends feedback message B to RAN device 1 , and correspondingly, RAN device 1 receives feedback message B.

[0328] The feedback message B is used by the RAN device 2 to feedback to the RAN device 1 at Xn whether the RAN device 2 supports this cooperative perception.

[0329] 1190. RAN device 2 sends perception signal #5 to RAN device 1. Correspondingly, RAN device 1 receives perception signal #5.

[0330] For example, the RAN device 2 sends a perception signal # 5 to the RAN device 1 based on the content of the cooperative perception request message 4 .

[0331] 11100, RAN device 1 measures perception signal #5.

[0332] That is, the RAN device 1 receives the perception signal #5 and completes the reception perception measurement with separate transmission and reception.

[0333] 11120, RAN device 2 performs self-sensing measurement.

[0334] That is, the RAN device 2 receives the sensing signal #5 sent by itself and completes the self-sensing measurement.

[0335] 11130. RAN device 2 sends feedback message C to RAN device 1. Correspondingly, RAN device 1 receives feedback message C.

[0336] The feedback message C is used by the RAN device 2 to feed back the self-sensing measurement result of the RAN device 2 to the RAN device 1 at Xn.

[0337] For example, a schematic diagram of the above method is shown in Figure 12, where the sensing entity is deployed in RAN device 1. As shown in Figure 12 (a), RAN device 1 sends a sensing signal to perform self-sensing detection, and RAN device 2 performs separate transmit and receive detection and sensing measurements. As shown in Figure 12 (b), RAN device 2 sends a sensing signal to perform self-sensing detection, and RAN device 1 performs separate transmit and receive detection and sensing measurements.

[0338] Hereinafter, another measurement method is introduced, in which the first network device does not support the perception management function, and the second network device does support the perception management function. As shown in FIG13 , the method includes:

[0339] 1310 , the first network device sends information # 6 to the second network device, and correspondingly, the second network device receives information # 6.

[0340] Message #6 is used to request the second network device to measure the target device. The second network device measures the target device in a manner including self-sensing and receiving measurement with separate transmission and reception.

[0341] 1320 , the second network device sends information # 7 to the first network device, and correspondingly, the first network device receives information # 7.

[0342] Information #7 is used to configure the first network device to measure the target device. The first network device measures the target device in a manner including self-sensing and receiving measurement with separate transmission and reception.

[0343] For example, information #7 indicates the configuration of perception signal #6, which is a perception signal sent by the second network device and can be received and measured by the first network. Information #7 can indicate parameter G, which includes at least one of the following:

[0344] the cyclic prefix corresponding to the sensing signal #6, the time-frequency resources carrying the sensing signal #6, the subcarrier spacing of the frequency domain resources carrying the sensing signal #6, the beam carrying the sensing signal #6, the receiving time window range of the first network device or the sensing distance range of the first network device or the transmitting time window range of the second network device,

[0345] Parameter G also includes the measurement quantity A (or measurement feedback quantity A):

[0346] The distance between the first network device and the target device, the speed of the target device, the angle of the target device, the time delay of the first network device receiving the sensing signal #6, the signal strength of the sensing signal #6, the Doppler frequency shift of the sensing signal #6, and the measurement time of the first network device.

[0347] Parameter G also includes

[0348] The components of the measurement quantity A in each multipath, the index of the beam carrying the sensing signal #6, or the type of the feedback quantity, where the feedback quantity is the measurement quantity A or the processed measurement quantity A.

[0349] For details, please refer to the previous article for the meaning of each parameter, which will not be repeated here.

[0350] In another example, information #7 indicates the configuration of perception signal #7. Perception signal #7 is a perception signal sent by the first network device, which can be received and measured by the first network, and can also be received and measured by the second network device.

[0351] For example, information #7 indicates parameter H, which includes at least one of the following:

[0352] The cyclic prefix corresponding to the perception signal #7, the time-frequency resources carrying the perception signal #7, the subcarrier spacing of the frequency domain resources carrying the perception signal #7, the beam carrying the perception signal #7, the receiving window time range of the first network device self-perception, the number of times the first network device sends the perception signal #7, receives the perception signal #7, measures the perception signal #7, and the feedback delay requirement.

[0353] 1330. The second network device obtains a measurement result.

[0354] The measurement result is determined based on measurement result A and measurement result B, where measurement result A comes from the first network device and measurement result B comes from the second network device. The measurement results are used to determine the perception characteristics of the target device.

[0355] The measurement result A is sent by the first network device to the second network device. For example, the first network device sends indication information to the second network device, where the indication information indicates the measurement result A.

[0356] The second network device supports SEMF and can process measurement results A and B. After processing the measurement results and obtaining the perceptual characteristics of the target device, the second network device sends the perceptual characteristics to the first network device. For example, the second network device sends indication information to the first network device, indicating the perceptual characteristics of the target device.

[0357] To facilitate understanding of the method of the embodiment of the present application, FIG14 shows a schematic diagram of a measurement process. RAN device 1 is used as an example of the first network device, and RAN device 2 is used as an example of the second network device. The following steps are included:

[0358] 1410. RAN devices acquire duplex capability and interact to determine whether the other party supports the SEMF function.

[0359] The duplex capability is sensed to be full duplex capability or half duplex capability, which affects the reception time of the sensing signal. In this example, the RAN device 2 supports SEMF.

[0360] 1420 , RAN device 1 sends a collaborative awareness request message 5 to RAN device 2 , and correspondingly, RAN device 2 receives the collaborative awareness request message 5 .

[0361] The cooperative awareness request message 5 may be sent at Xn, and is used to request the RAN device 2 to perform cooperative awareness.

[0362] 1430 , RAN device 2 sends a feedback message R to RAN device 1 , and correspondingly, RAN device 1 receives the feedback message R.

[0363] The feedback message R may refer to the description of the above information #6, and is used to configure the self-sensing measurement and feedback of the RAN device 1 at Xn.

[0364] 1440 , RAN device 2 sends a feedback message T to RAN device 1 , and correspondingly, RAN device 1 receives the feedback message T.

[0365] The feedback message T can refer to the description of the above information #7, and is used to configure the RAN device 1 to receive the perception signal from the RAN device 2 and measure and feedback it at Xn.

[0366] 1450. RAN device 2 sends perception signal #6 to RAN device 1. Correspondingly, RAN device 2 receives perception signal #6.

[0367] 1460 , RAN device 1 measures perception signal # 6 .

[0368] That is, the RAN device 1 receives the perception signal #6 and completes the reception perception measurement with separate transmission and reception.

[0369] 1470 , RAN device 2 performs self-sensing measurement.

[0370] That is, the RAN device 2 receives the sensing signal #6 sent by itself and completes the self-sensing measurement.

[0371] 1480. RAN device 1 sends perception signal #7 to RAN device 2. Correspondingly, RAN device 2 receives perception signal #7.

[0372] For example, the RAN device 1 sends a perception signal #7 to the RAN device 2 over the Uu air interface or link based on the content of the information #7.

[0373] 1490 , RAN device 1 performs self-sensing measurement.

[0374] That is, the RAN device 1 receives the sensing signal #7 sent by itself and completes the self-sensing measurement.

[0375] 14100, RAN device 2 measures perception signal #7.

[0376] That is, the RAN device 2 receives the perception signal #7 and completes the reception perception measurement with separate transmission and reception.

[0377] 14110 , RAN device 1 sends measurement result E to RAN device 2 , and correspondingly, RAN device 2 receives measurement result E.

[0386] 1610 , the third network device sends information # 8 to the first network device, and correspondingly, the first network device receives the information # 8 .

[0387] Information #8 (an example of the fifth information) is used to configure the first network device to measure the target device, for example, to configure the first network device to perform self-sensing and / or to configure the first network device to perform transmit-receive separation sensing.

For example, the parameter J further includes at least one of the following: a cyclic prefix corresponding to the sensing signal of the second network device, a time-frequency resource carrying the sensing signal of the second network device, a subcarrier spacing of a frequency domain resource carrying the sensing signal of the second network device, a beam carrying the sensing signal of the second network device, and a receiving window time range of the first network device.

[0390] For details on the explanation of each parameter, please refer to the above description and will not be repeated here.

[0391] 1620 , the third network device sends information # 9 to the second network device, and correspondingly, the second network device receives the information # 9 .

[0392] Information #9 (an example of the sixth information) is used to configure the second network device to measure the target device, for example, to configure the second network device to perform self-sensing and / or to configure the second network device to perform transmit-receive separation sensing.

[0393] Configuring the self-awareness of the second network device: Information #9 indicates parameter K, which includes at least one of the following:

[0394] The cyclic prefix corresponding to the perception signal, the time-frequency resources carrying the perception signal, the subcarrier spacing of the frequency domain resources carrying the perception signal, the beam carrying the perception signal, the receiving window time range, the number of sending and receiving measurements, and the second feedback delay requirement, wherein the second feedback delay requirement is used to determine the time for the second network device to feedback the measurement results to the third network device.

The measurement result J includes the self-sensing result and / or the transmission-reception separation sensing result of the first network device, and the measurement result K includes the self-sensing result and / or the transmission-reception separation sensing result of the second network device.

[0402] Optionally, the third network device may further feed back the perception characteristics of the target device to the first network device and / or the second network device.

[0403] In this method, the third device coordinates the perception of the first network device and the second network device to obtain the perception characteristics of the perception target, without requiring signaling interaction of the target device, thus saving the overhead of the target device.

[0404] To facilitate understanding of the method of the embodiment of the present application, FIG17 shows a schematic diagram of a measurement process. RAN device 1 is used as an example of the first network device, RAN device 2 is used as an example of the second network device, and RAN device 0 is used as an example of the third device. The following steps are included:

[0405] 1710. RAN devices acquire duplex capability and interact to determine whether the other party supports the SEMF function.

[0406] The duplex capability is sensed to be full duplex capability or half duplex capability, which affects the reception time of the sensing signal. In this example, RAN device 0 supports SEMF.

[0407] 1720 , RAN device 1 sends a perception requirement message to RAN device 0, and correspondingly, RAN device 0 receives the perception requirement message.

[0408] The perception requirements can refer to the perception requirements described above and will not be repeated here.

[0409] Optionally, the third device may also be a non-RAN device, such as a CN device, and the perception requirement may also come from the CN, and the third device obtains the perception requirement through the CN.

[0410] 1730 , RAN device 0 sends information # 8 to RAN device 1 , and correspondingly, RAN device 1 receives information # 8 .

[0411] 1740 , RAN device 0 sends information # 9 to RAN device 2 , and correspondingly, RAN device 2 receives information # 9 .

[0412] 1750. RAN device 2 sends perception signal #A to RAN device 1. Correspondingly, RAN device 1 receives perception signal #A.

[0413] For example, the RAN device 2 sends a perception signal to the RAN device 1 at Uu according to the content of the information #9.

[0414] It should be understood that RAN device 1 and RAN device 2 may transmit perception signals to a target device or within a potential target detection range. The perception signals are then reflected by the target device and reach the perception signal receiving end. For ease of description, this application will simply describe RAN device 1 transmitting the perception signal to RAN device 2, or RAN device 2 transmitting the perception signal to RAN device 1. The steps involved in transmitting the perception signal in this application can be referred to as described herein.

[0415] 1760 , RAN device 2 completes self-sensing measurement.

[0416] For example, the RAN device 2 completes self-sensing measurements at Uu.

[0417] 1770 , RAN device 1 measures perception signal #A.

[0418] 1780. RAN device 1 sends perception signal #B to RAN device 2. Correspondingly, RAN device 2 receives perception signal #B.

[0419] For example, RAN device 1 sends perception signal #B to RAN device 2 at Uu according to the content of information #9.

[0420] 1790 , RAN device 1 completes self-sensing measurement.

[0421] For example, the RAN device 1 completes self-sensing measurements at Uu.

[0422] 17100, RAN device 2 measures perception signal #B.

[0423] 17110. RAN device 1 sends a feedback message #Q to RAN device 0. Correspondingly, RAN device 0 receives the feedback message #Q.

[0424] The feedback message #Q indicates the measurement result obtained by the RAN device 1, such as measurement result J.

[0425] 17120. RAN device 2 sends a feedback message #W to RAN device 0. Correspondingly, RAN device 0 receives the feedback message #W.

[0426] The feedback message #Q indicates the measurement result obtained by the RAN device 2, such as the measurement result K.

[0427] 17130 , RAN device 0 processes measurement result J and measurement result K.

[0428] For example, the RAN device 0 calculates and processes the measurement result J and the measurement result K in a unified manner.

[0429] 17140. RAN device 0 sends a feedback message #S to RAN device 1. Correspondingly, RAN device 1 receives the feedback message #S.

[0430] For example, RAN device 0 sends a feedback message #S to RAN device 1 at Xn. The feedback message #S is used to indicate the perception characteristics of the target device, or in other words, to indicate the perception recognition result.

[0431] Optionally, the RAN device 0 may also send a feedback message to the requester of the sensing requirement, where the feedback message indicates the sensing characteristics of the target device, or indicates the sensing identification result. The requester may be the one that initially sends the sensing requirement to the SEMF of the CN.

[0432] For example, a schematic diagram of the above method is shown in Figure 18 , where the sensing entity is deployed in RAN device 0. As shown in Figure 18 (a), RAN device 1 transmits a sensing signal to perform self-sensing detection, while RAN device 2 performs separate transmit-receive reception detection and sensing measurement. As shown in Figure 18 (b), RAN device 2 transmits a sensing signal to perform self-sensing detection, while RAN device 1 performs separate transmit-receive reception detection and sensing measurement. RAN device 0 collects measurement feedback from RAN devices 1 and 2, centrally processes it, and obtains measurement and sensing results, which it then feeds back to RAN device 1.

[0433] It should be understood that when the third party is a RAN device, the interface between it and RAN device 1 and RAN device 2 is Xm. If the third party is a CN device, it can be another interface, such as Nm. When the third party is a UE, the interface with device 1 and device 2 is a sidelink, for example, device 1 and device 2 are each a UE.

As another example, the measurement method of the present application can also be applied to a network composed of UEs, such as when the SEMF is located in the UE, and perception signaling transmission occurs between UEs, for example, using a sidelink for perception signaling transmission and perception signal transmission. In the above example, the RAN network device and / or the UE is responsible for sending and receiving perception signals, and the SEMF is used to synthesize and calculate based on the perception measurement results to obtain the results required by the perception target, such as geographic location, distance, speed, angle, map, posture, imaging, material, etc.
